Traditional door locks consist of several key components, each with a specific function to ensure the lock operates smoothly and securely. Here are the main parts of a door lock:
The part you turn to operate the lock. Knobs are typically found on older locks, while levers are common in more modern designs. Levers are generally easier to use, making them a popular choice for both residential and commercial properties.
The mechanism that accepts the key. The cylinder contains pins and tumblers that align with the key to unlock the door. Cylinders can vary in complexity, with some offering higher security features such as anti-pick and anti-drill protection.
The metal plate attached to the door frame. The latch or bolt extends into the strike plate to keep the door closed. The strike plate is crucial for security, as it reinforces the door frame and helps prevent forced entry.
The movable metal piece that extends into the strike plate. It retracts when the knob or lever is turned, allowing the door to open. Latches can be spring-loaded or deadlocking, with deadlocking latches providing additional security by preventing the latch from being pushed back when the door is closed.
In some locks, a bolt extends from the door into the frame to secure the door. Bolts are often found in deadbolt locks and provide a higher level of security compared to latches.
The metal plate affixed to the door edge where the latch or bolt exits the lock. It adds strength and durability to the lock mechanism, protecting the internal components from wear and damage.
The decorative plate surrounding the knob or lever. It can also protect the lock cylinder from tampering. Escutcheons come in various designs and finishes, adding aesthetic appeal to the door while also providing functional benefits.
Understanding the parts of a key is crucial for comprehending how a lock functions. A typical key has the following parts:
The part of the key that you hold. It’s usually the widest part and often has a unique design for grip and identification. The bow can be customized with different shapes and logos, making it easy to identify specific keys.
The long, flat part that is inserted into the lock. The blade contains the key's cuts or bittings. The length and width of the blade can vary depending on the lock type.
The notches along the blade that correspond to the lock's pins or wafers. Each cut is at a specific depth to align with the pins inside the lock cylinder. The precise arrangement of cuts makes each key unique.
The part of the key that stops it from being inserted too far into the lock. It ensures the cuts align correctly with the pins. The shoulder also helps prevent damage to the lock and key by limiting how far the key can be inserted.
The end of the key that is first inserted into the lock. The tip guides the key into the keyway and starts the alignment process with the lock pins.
Deadbolts offer an extra layer of security compared to traditional door locks. Here are the main components of a deadbolt lock:
The strong metal piece that extends into the door frame to secure the door. Deadbolts usually have a longer, more robust bolt than standard locks, making them more resistant to forced entry.
The interior mechanism used to operate the deadbolt without a key. It allows you to lock or unlock the deadbolt from inside. Thumb turns provide convenience and quick access in case of an emergency.
Similar to traditional locks, the cylinder in a deadbolt accepts the key and contains the pin and tumbler mechanism. High-security cylinders may feature additional protections against picking, drilling, and bumping.
The metal plate attached to the door frame that the bolt extends into. It often includes a reinforced box for added security. The strike plate is essential for withstanding force and preventing kick-ins.
The metal plate on the edge of the door where the bolt exits the lock mechanism. It provides a finished look and adds strength to the door edge, reducing wear and tear on the lock components.
The plate behind a door knob is known as the escutcheon. The escutcheon serves both a decorative and protective function, covering the hole in the door and providing a finished look. It also helps protect the lock cylinder from tampering and damage. Escutcheons are available in a wide range of styles and finishes, allowing you to match them with your door hardware and overall decor.

Euro cylinder locks, also referred to as barrel locks, profile cylinder locks, or pin tumblers, are among the most common types of locks used across Europe. Their simplicity and versatility make them ideal for both internal and external doors. One of their standout features is the ability to replace the cylinder without needing to remove other door fittings, making them easy to install and highly popular in both residential and commercial properties.
Choosing the right lock can be overwhelming, but our buyer’s guide will help you make an informed decision. Below, we explain the different types of euro cylinders, their setups, security features, and how to select the best one for your needs.
Key to key cylinders feature a keyhole on both sides of the door, allowing the door to be locked or unlocked from either side. This is typically used for high-security areas, such as front and back doors, as it provides additional protection. Even if a burglar breaks the glass, they would still need the key to unlock the door.
This hybrid lock combines a thumb-turn mechanism on one side and a keyed lock on the other. The thumb-turn allows easy internal locking without a key, making it ideal for situations where quick exit is required, such as in apartments with fire safety regulations.
These cylinders provide keyed access from just one side, commonly used for external access on doors like garage doors.
These locks feature a thumb-turn mechanism on one side for easy locking and unlocking without a key, while the other side requires a coin. They are useful for situations where privacy or quick access is needed, such as bathrooms or small offices.
When selecting a euro cylinder, you’ll need to consider several factors, including security, door type, and lock length. Here’s what to keep in mind:
Euro cylinder locks offer a range of security features designed to protect against common methods of forced entry:
These cylinders are reinforced with a sacrificial snap line, allowing the cylinder to break under pressure without compromising the locking mechanism. This is essential for external doors vulnerable to lock-snapping attacks.
Anti-pick locks are built to resist manipulation by tools used in lock-picking, making them highly secure against burglary attempts.
Anti-drill locks are equipped with hardened steel pins that make it difficult for burglars to drill into the lock and bypass the mechanism.
Anti-bump locks are designed to prevent bump key attacks, a technique that involves using a specially adapted key to manipulate the lock pins and open the door. These locks are ideal for protecting against subtle, low-damage break-ins.
Euro cylinders are suitable for both internal and external doors, but the lock type you choose will depend on the door’s position and security needs.
External Doors: For front, back, side, or patio doors, opt for a 6-pin cylinder lock for better security.
Internal Doors: 6-pin cylinders are also suitable for internal doors, especially in office spaces or rental properties. However, if fire safety is a concern, you’ll need a thumb-turn euro cylinder for easy escape.
Euro cylinders are compatible with a variety of door materials, including uPVC, wood, composite, aluminum, and steel.
It’s crucial to choose the correct cylinder length to ensure the security of the door. A cylinder that protrudes too far is vulnerable to being snapped, while a cylinder that is too short may collect moisture and dirt, affecting its performance. Measure the existing lock or door carefully to select the appropriate length.
Euro cylinder locks rely on a series of pins of varying lengths to prevent the lock from opening without the correct key. The correct key aligns the pins, allowing the lock to turn. A greater number of pins typically offers higher security.
While older models may have been vulnerable, modern euro cylinders offer robust security features that protect against common break-in methods. It’s important to purchase from a reputable provider and choose a lock that suits the level of security needed for your property.
Yes, many euro cylinder locks are reversible, meaning they can be installed either way on the door as long as the door thickness is compatible.
Euro cylinder locks offer a versatile and secure solution for both residential and commercial properties. By understanding the different types of euro cylinders, their security features, and how to choose the right one for your needs, you can ensure your property remains safe and secure.
